LUBRICATO R.

SPECIFICATION forming part of Letters Patent No. 256,869, dated April 25, 1882.

Application filed August 10, 1881. (Xoinodch) To all whom it may concern Beit known that I, LUTHER BYRON BAILEY, a subject of the Queen of Great Britain, residing at the city of London, in the county of Middlesex, in the Province of Ontario, Canada, have invented a new and useful Lubricator, of which the following is a specification.

My invention consists ofa lubricator in which the steam-inletand lubrican t-outletarethrough one and the same passage, thereby requiring only one connection' from lubricator to the steampipe or steam-chest. This is effected by a valve-chamber of peculiar construction, in combination with a lubricant-reservoir and gage-glass.

The construction and operation will be more particularly explained with reference to the accompanying drawings, wherein Figure l is a side elevation of my invention. Fig. 2 is an end view of same. Fig. 3is a vertical section, and Fig. 4 is a horizontal section, of valve-chamber.

P is a steam-pipe or steam-chest, to which the lubricator L is screwed or otherwise connected.

R is alubricant-reservoir, at bottom of which is valve-chamber V, containing'valves O O; and Gis a gage-glass for the purpose of noting the supply of the lubricant to the steam-pipe or steam-chest, and to tell when the lubricant has run out.

0 is the cap of the lubricator, through which the lubricant is introduced into the reservoir R. The steam from the steam-pipe enters valve-chamber V (the construction of which is shown more particularly in Figs. 3 and 4) through passage S, and the steam acts on the oil in reservoir B through either valve, ac-

cording as the valves are more or less open. The reservoir R has communication with the passage S through two ducts: first, through the passages r ands, and, second, through the gage-glass Gr (entering the reservoir at g) and passages r and 8. By closing valve 0 and opening valve 0 the steam enters the oil-reservoir R directly from valve-chamber V and presses on the oil, and by slightly opening the valve 0 the steam forces the lubricant out of reservoir R at side, down through gage-glass G into the valve-chamber V, and delivers the lubricant at the back of the valve 0, which regulates the supply of oil passing into the steam-pipe through passage S. If by accident the passage S through the gage glass G should become choked or stopped up from any cause whatever, by closing valve 0 and opening valve 0 the steam is forced directly from valve-chamber through the gage-glass and blows out the obstruction, which forces the oil out of the reservoirR at the bottom into valvechamber, the supply of oil to the steam-pipe or steam-chest in this case being regulated by the distance the valve 0 is opened.

Having thus described my invention, I claim- Thecombination, with reservoir R, having steannpassage r at bottom and oil-outlet g at top, of valve-chamber V, having communication with said reservoir at bottom through the valve-passage r s, and at top through theoutlet 9', glass tube G, and valved passage 1' s, as set forth.
